A new book about Zumpe and his pianoforte

Until now, no book had ever been written exclusively about Zumpe and his pianoforte. So, this is the first publication devoted solely to this maker and his formidable instruments. It was sparked by the Barcelona Music Museum’s restoration project for the 1776 Zumpe & Buntebart pianoforte after a lengthy process of research and study carried out by the German restorer Kerstin Schwarz.

Pablo Gómez Ábalos, the editor and co-author of this book, highlights that this “sophisticatedly simple pianoforte designed and constructed in 1766 by Johannes Zumpe (1726-1790) was the true driving force behind the piano’s social, commercial, and creative route forward”. Hence, the book spotlights a constructor and an instrument that are both of cardinal importance in piano history and places the instrument in its social context. On the other hand it thoroughly shows the whole restoration process.

The articles of the book are written by credited specialists on the matter such as Michael Cole (Scholar, Harpsichord and Pianoforte maker and restorer), Pablo Gómez Ábalos (Freelance scholar, fortepianist and clavichordist), Kerstin Schwarz (organologist, early keyboard instrument maker and restorer) and Marisa Ruiz Magaldi (Curator of Museu de la Música de Barcelona).
